PACKET SCHEDULING IN A WIRELESS LOCAL AREA NETWORK

摘要

PURPOSE: A packet scheduling device and a method thereof are provided to supply a packet of a traffic flow to schedule the packet. CONSTITUTION: A queuing device(506) stores a packet in a transmission queue about corresponding AC from a traffic flow. A selection device(508) selects a packet in a transmission queue from an AC by using a QoS based contention resolution function. A transmitting device(510) transmits a selected packet through an antenna. A collision detecting device(514) detects whether a selected packet collides with other packet while transmitting. A competition solving device(516) solves collision between selected packet and other packet even if collide has occurred.
